Kelvin: Optics for smartphones. Focus on What Matters!
Kelvin: Optics for smartphones. Focus on What Matters!

This digital project blurs the lines between the convenience of mobile photography and the power of professional optics.

The Levenhuk Kelvin Touch KM3 is a digital photomicroscope that doesn’t require a built‑in screen. Instead, it streams live images over Wi-Fi directly to your smartphone or tablet. You get a real-time view on your own screen and can control all of the shooting settings from the mobile app. Explore the microworld and share your discoveries with just a few taps!

No more looking into eyepieces or straining your eyes to see the fine details. The microscope creates its own Wi-Fi hotspot. Simply connect via the mobile app and then the live image appears instantly on your smartphone or tablet. Saving what you see is easy: snap photos, record videos, and share them immediately.

Magnification ranges from 50x to 1900x. The lowest setting is perfect for studying the overall structure of a sample, like a leaf cross-section or a drop of lake water. Push it to the maximum, and individual plant cells or tiny salt crystals come into sharp view.

The mechanical stage moves your sample smoothly along two axes, making it easy to locate, lock in, and measure any specific area. Coarse focus helps you find the right zone quickly, while fine focus helps you dial in perfect clarity.

Adjustable LED illumination lets you observe any sample type. Use the lower illumination for transparent specimens like tissue slices or liquids and then switch to the upper illumination for opaque objects like coins, minerals, or insects. The device runs on either AC power supply or its built-in battery, which is perfect for the classroom, countryside, or outdoor exploration.

The Levenhuk Kelvin Touch KM3 is perfect for anyone who wants to experience discovery and create great content without any hassle.
